useful Improvement in Box Stitchers, of

which the following is a full, clear, concise, and exact description, reference being chad to the accompanying drawings, forming 1 a art of this specification.

y invention relates to box stitchers and has to do more particularly with the pro vision of an improved form of construction of clincher block and support therefor 00- operable with the stitcher head for sealing fibre shipping boxes having an overlapping flange and flat box cover. One of the features of my invention is the provision of a stitcher for sealing fibre shippin boxes having an inturned flange around t e edge of the box with a flat cover therefor and provided with a stitcher head for drivin the metallic fasteners through the cover an flange, and a clincher block for insertion beneath the flange and having a support so constructed that the clincher block may be inserted beneath the cover and flange, the support being such that it may extend outwardly between the cover and flange and preferably beyond the edge of the cover so that the block may be moved along beneath the flange to stitch the overlappin portions of the cover and flange and sea the box around the entire edge, at the same time permitting the withdrawal of the block and support between stitches. When using the device to seal the cover to the flange of a filled box, the block'a-nd support are so constructed as to be capable of clinching the fas- 40 tener without any additional support beneath the clincher block and at the same time permit movement of the block around the entire edge of the box including the corners thereof and then withdrawing the support and block from the box leaving the box sealed around the edge. Thus the box is sealed so. as to prevent a ready opening thereof, the clinc ing of the metallic fasteners being such that amutilationof the and an unwarranted opening thereof may be readily detected. a

In the accompan ing drawings I have shown the preferred form of mylinvention cover is necessary in order to open thebox together with the preferred type of box on which it is used and in which Fig; 1 is a side elevation of a common form of stitchin machine with my inven- 131011 incorporated therein;

F 1g. 2 is a side elevation of the clincher block and supportin means;

Fig. 3 is a front e evation of the same; i

F 4 is a plan view thereof;

Fig. 5 is a sectional view along the line 5 5 of Fig. 8 showing the position of the chncher block beneath the overlapping portions of the box;

Fig. 6 is 8; 1g. 7 is a plan view of one form of box adapted to. be operated upon; and.

Figs. 8, 9, 10 and 11 show the different relat1ve positlons of the box and clincher block and support as the box of Fig. 7 is moved around in sealing the cover.

Referring now to the machine as shown 1n F igs. 1 to 6, my invention is adapted for use in applying metallic fastenersto fibre shipping boxes and for this purpose I have shown a well known type of machine a section along line 6-6 of v adapted for driving the usual so called wire staple, the machine including the usual body portion 15 car ing the stapling head 16 operated by a elt driven pulley 17 controlled by a treadle 18. An adjustable table 19 is provided being carried by the body portion 15 and movable up and down by ordinary rack and pinion mechanism 20. Thus the machine may be accommodated for boxes of various thicknesses, the table 19 being movable relative to the clincher block so that it may be inserted beneath the cover of the box.

The preferred form of clincher block and supporting means therefor is shown more in detail in Figs. 2 to 6 and comprises a clincher block preferably in the form of a plate which need be only of such dimensions contents thereof without e acting the loss of an undue amount of waste space. This clincher block 21. is preferably so supported as to receive a staple clinching recess 22 and I that it may be insertedbetween an inturned cover supporting'flangeand the cover withthe fastener is driven therethrou h. In th form of my invention as shown erei this 23 which extendsfbetween he ange-and cover, and is raised above the; clincher block 21 by the upturned portion 24 so aslto p'ro 10. This permits placing a staple at a. as to hem the position indicated in Fi through the overlapping portions. The next side is now drawnytoward the operator and stitched and the box moved untilit is sealed a around,i the staples being indicated at A, B, C and'D-tocorrespond with the mark of Figs. 8 tell.

in s 1 'con'str ction includes afs'u rtin element 510w m connection with the operation. of u v I ppo Lstapl .the box at the cornersit is to be noted t at the clincher blockand. support are soaconstructe'd that the block may'be vide a space- 25 through which the lowerboxplaced beneath the overlapping portions at portion may readily pass. i

This portion-23 is also of a dimension and construction sufiiciently rigid to an portthe block so as to take the impact as t e-s'taple p is driven through and clinched, without additional support beneath "the clincher. block)? the corners and placing fasteners through.

the overlappin portions. thereat. In order to attach the incher block and support. to the staple head an upturned bracket 26 is provided of a shape suitable to be securely fastened to the'staple head in such a manner that the clincher block will be positioned beneath the staple driving element. It will, of course, be apparentthat the clmcherblock and supporting means may be usedin connection with various makesof stitchers or machines for driving various types of metallic fasteners, the shape, size, etc., of the bracket 26 being determ ned by the particular machine with which it cobperates. H In Fig. 7 I have shown a plan view of one form of box on which the device is designed v to operate, this box being rectangular and provided with ,four sides each one of which as'an inturned flange 27, and a-flat cover 28, the box'shown being of the usual fibre construction used for shipping contalners, of

' and cover 28 stitched together at A.

7.) The box is now'drawn toward the-operator, movin the clincher block 21 alon beneath the an or inturned edge 27 o the box, the bloc support '23 moving along between the flange and cover. At proper.

points along the side, staples. are driven through the cover and flange to secureli" stitch them together. As the clincher bloc nears the first corner of the box the box is turned as indicated in Fig. .9 so as to place a. staple through the overlapping ortions at 'B after which the box is turned 3 ill further to A.

he corner ofthe box so as to securel seal it at this oint. In order to accomplis this I prefera ly construct the clincher block with rounded'corners 31, 32 .and inset the support portion 241MB? far'enough to clear the edge Y of -the inturned flap not onl as the blockv is I Also thesupport and block are 'referab 'movedialong. the straight si e of the box but also. at thecorners thereof. Also this construction-is such that the clincher block is sup orted to such an extent that it. will, wit out any additional support beneath. the

block, take the impact as the metallic fastener is driven andclinch it beneath the' For sealing the box around its edge I start at A and continue along the four sides The last corner is sealed at D' and the bloek then withdrawn from the box. In Fig. 11 I have shown how the. clincher block is drawn between the side and end' flanges 27 as the last staple is driven at'D. In order to permit a ready withdrawal of the clincher block from the box at this last point, the

block is rounded at 35 as shown in Fig. 2,

so-that as the box is drawn toward the operator the rounded edge of the block will find it's way between th flanges 27 as indicated in Fig. 11 and a s iaple driven at D after which the block is withdrawn from the box.

In describing theloperation of the device I have shown one form of box and one method of sealing the cover thereof but it will be apparent that my invention is not limited to the sealing-of any particular kindof box or sealing a box as in Fig. 7 in the particular way described. Also I contemplate emplo ing my invention in other ways than that s own and described and do not desire to be limited to the exact structures comes within the spirit and scope of the ap ended claims.

at I claim as new and desire to cover by Letters Patent is 1. In a stitcher for sealing fibre shipping boxes havin an inturned flange around the edge of the ox and a flat cover therefor, a stitcher head, a short clincher block for insertion beneath the flange, a su port for the disclosed but aim to cover all that which clincher block extending inwar y then rearwardly and angularly upwardly and then outwardly above and over the flange beneath the cover and beyond the ed e thereof whereby the block may be move along beneath the flange so as to stitch the flange and cover along their overlapping portions, said support being of dimensions and construction to be capable of clenching the staples without any additional support beneath the clincher block.

2. A machine for sealing a fibrous shipping case having a flap inturned around the outer wall with a flat cover while the contents of the case remain therein, comprising, in combination, a driver for driving metallic fastenings, a rigid arm that extends transversely of and under the inner face of the cover, a flat anvil support that extends from the arm forwardly and angularly downwardly then transversely beneath the flap on a side wall, and an anvil rigidly supported by the anvil support, means for rigidly supporting said arm and anvil from a position above the case being sealed, and means for actuating the driver to drive metallic fastenings throu h the adjacent edges of the cover and the ap on a side wall as they are fed over the anvi In witness whereof, I hereunto subscribe my name this 3rd day of November, A.
